Abstract

[PROBLEMS] To sandwich a precision machine part that is in a deep position and orthogonal to a sliding part, to sandwich a tissue in a deeply bent position during a surgical operation, or to bond a paper craft or the like. Provided is a slide type tweezer that can work without problems even when it is difficult to work at a position orthogonal to tweezers. SOLUTION: A base portion 1 including an index finger rest portion, a middle finger rest portion, and a sandwiching portion 1c; a sliding portion 2 comprising a thumb rest portion and the other sandwiching portion 2c; It has a pulling spring 3 that keeps the holding part of the moving part in a normally open state, and is configured so that the holding part comes into close contact by narrowing the intervals between the index finger contact part, the middle finger contact part, and the thumb contact part. Features. [Selection] Figure 2

Description

  The present invention is a slide type tweezer, more specifically, pinching a deep member such as a precision machine, holding a tissue in a deep surgical field such as a surgical operation, or bonding a bond in a paper craft work etc. Some of them relate to sliding tweezers that make work that could not be done easier.

  Since conventional tweezers are used by holding the parallel shape from both sides by hand, there is no problem in sandwiching tissue in the surgical field and precision machine parts in a wide area, but in a deep area in a narrow area In particular, it was actually impossible to pinch tissue or parts in a bent position. In order to solve this problem, a structure has been proposed in which the base portion and the sliding portion are slid and held.

  As described above, conventional tweezers are effective in places that are parallel to the gripping part and easily reachable by hands and fingers, but on the contrary, work on narrow and deep parts may take time or may not be possible. It was.

  In this device, when the index finger and middle finger are attached to the base and the thumb is pressed against the sliding part, the pulling spring extends, and the base part side claw is used as a guide to bring the sliding part holding part and the base side holding part into close contact with tweezers. It is a thing that plays the role of.

  According to the slide type tweezers of the present invention, it is possible to securely hold the parts of precision machines that are in a deep position and perpendicular to the sliding direction, and tissues that are bent in a deep surgical field in a surgical operation. It is possible to pinch a narrow and deep place with a paper craft etc. and a place perpendicular to the gripping part.

It is a top view of the present invention. It is a front view of the present invention.

The configuration of an embodiment of the present invention will be described with reference to FIGS.
The sliding tweezers of the present invention is composed of a base 1, a sliding part 2, and a tension spring 3. A base side index finger rest part 1a and a base side middle finger rest part 1b are provided at one end of the base part 1. At one end of the sliding portion 2, a sliding portion side thumb rest portion 2a is provided at a position facing the base side index finger rest portion 1a and the base side middle finger rest portion 1b of the base portion 1. At the other end of the base portion 1, a base side clamping portion 1 c is provided, and at the other end of the sliding portion 2, a sliding side clamping portion 2 c is provided. The base portion 1 is provided with a base side guide claw 1d for sliding the sliding portion 2, and a base side spring mounting portion 1e in the vicinity of the index finger rest portion 1a and the base side middle finger rest portion 1b of the base portion 1. The sliding portion 2 is provided with a sliding portion side spring mounting escape hole 2d for the base side spring mounting portion 1e, and at the position where the tension spring 3 is held in a contracted state. 2b is provided.

The handling of the sliding tweezers will be described. When the index finger is applied to the base side index finger rest part 1a, the middle finger is applied to the base side middle finger contact part 1b, and the thumb part is applied to the sliding part side thumb pad part 2a and pushed in, the tension spring 3 which is normally contracted is extended The base side clamping part 1c and the sliding part side clamping part 2c are brought into close contact with each other and serve as tweezers.
In this embodiment, the bending angle of the sandwiching portion is described as a right angle. However, the obtuse angle or the acute angle may be used, or the tip shape of the sandwiching portion may be narrowed or widened. Also, a resin-made part may be attached to the base side index finger rest part 1a, the base side middle finger rest part 1b, and the sliding side thumb rest part 2a, or a cover-like part may be attached to the base side guide claw part. . However, when considering disinfection and hygiene, all stainless steel is desirable.
